METHOD FOR MAKING FLOAT GLASS HAVING REDUCED DEFECT DENSITY |
摘要 |
<p>A method for reducing the defect density of glass comprising melting a glass composition comprising from 65-75 wt.% of SiO2; from 10-20 wt.% of Na2O; from 5-15 wt.% of CaO; from 0-5 wt.% of MgO; from 0-5 wt.% of Al2O3; from 0-5 wt.% of K2O; from 0-2 wt.% Fe2O3; and from 0-2 % FeO, wherein the glass composition has a total field strength index of greater than or equal to 1.23 is disclosed.</p> |
